MACHINE FOR QPERATING N HEELS.

l f Application led October 17, 1925. Serial No. 63,148.

This invention relates to machines for operating upon the heels of' boots and shoes and is illustrated as embodied in a machine 1 `for trimming the breast portions of heels,

5 for example'Louis heels. The invention is illustrated as embodied in a machine of the type disclosed in United States Letters Patent No. 1,426,354, granted August 22, v"11922, on application of D. W. Bunker. i

Y .'Machines of this type comprise a rotary outter and a work support against which the tread face of the shoe is 'held and between which and the cutter there is relative movement to carry the heel across the acting face-of the cutter. In Order that the proper amount' may beremoved from the heel breast it isv necessary to locatethe heel accurately longitudinally, and when, vaccording to t-he p y:usual practice, a gage is provided on' the shoe support to engage the breast face of 'the heel, 4the gage musthave very slight extent heightwise of the heel in Order notl u ,to interfere with the action of the cutter upon the heel breast.v On the other hand, 'unless' a ga-geiof substantial height is provided, the proper location ofthe heel is dif-VV f V projection 24 from the column 2 and extend- Y ficult to obtain and maintain.

. l@lojectsY of this invention are to provide fan adequate gage for locating the heel lon-1 gitudinally'whichf will not interfere with the action of th'ecutte'r upon `the heel.

Features of the invention consist in an organization comprising a rotary vcutter and *ash'oe support or carrier,` the cutterand carrier being arranged 'for relative movemeiitf to 'present fthe.` shoe to the cutter, and a gage against lwhichthe breast face' of the .heel'may be held prior .to rsaid relative movement of the cut-terl andy 'carrier ybut vwhich does not remain in contactwith the Iheel when the latter`v and the cutter -are brought together." As illustrated,the shoe carrier isV arranged Ifor-movement relatively to the cutter' and the gage, and'is normallylbelow the cutter, the rgage'being arranged'to engage theheel when the carrier isin itsv lowest positionjand to remain stationaryduring'the movement of the carriery toward the cutterV so.. that Athe heel is carried awa-y `from the gage and across the field of 'action of they n cutter whichthereforeracts upon the heel? without anypossible chance'of interferencer ,with its'l action by the gage;`

These and other'features of the invention "which is utilized as a gage for locating the heel longitudinally by engagement with its breast face. vA square, hollow fit-ted to slider on the upper portion of the 'formed on a projection 48 extending for- Yby engagement with its treadV will appear more fully from the following detailed description when read in connection with the accompanying drawing and will be pointed out in the appended claims.

In the drawing, i

Fig. is a side elevation of a machine embodying. the present invent-ion, l Fig. 2 is aplan view of the shoe-positioning devices, and I Fig. 3 is a perspective View, partly in section, of the gage for locating the breast edge of the heel.

Referring to Fig. l of the drawings, the numeral 2 indicates the column of the machine oii the upper portion of which is a head 4 having bearings for a cutter shaft l0 arranged to be driven from a suitable source of power. On one end of the shaft 10 is a cutter-head 14 having two fly cutters 16 the cutting portions of which are shaped to give the proper contour to the breast edge of a Louis'heel. The shoe-supporting and carrymg'inechanism is mounted on a long, downv wardly extending bracket 2O which, near its upper end, has a dovetailed portion 22 arranged to slide in a guideway formed in a which it can be turned.

-Pivoted at v34 to the lower end of the bracket 20'is a` clamping member 36 through which a shaft 38v extends. lthe clamping 90 member being tightened On the shaft by a bolt 40.y 4The shaft 38 extends upwardly to a point beneath the cutter-head 14 where it is yreduced to form a heel-locating gage. As shown in Figs. 2 and 3,.the reduction of the shaft' consists in cutting away about thre-e-fourthsof its cross-section, leaving a segmental portion 42 one flat face 44 of post 46 is shaft '38 and is guided by opposite fiat facesV wardly from lthe bracket 20; A member 50v 105 'which carries means forlocatin@ the shoe face issecured by a clamping4 bolt 52V to the upper Y engages is at right angles to the surface 14T ot the 12 against which' the breast 'tace o1 the topl'itt is positioned, and that the surface 58- is arranged tar enough back ot' the front edge oi the surface A so that an ,adequate 'portion ot the gagging surface 114 is exposed.

` the" lever 86.

In order to hold a shoe wlriclihas been located by the positioning" means 56, 5@ and42, a pair ot jaws 60, 62 is provided'. These jaws are pvoted byV pins to the member 50 and havel interengaging teeth so that when one j aw is moved the other will be moved equally and oppositel'y. The amount ot' initialf separation otY the jaws is determined by a'fscrew 68 which is threaded through an arm of the jaw 62 and engages a pro-jee tion T2011 the jaw 60.

Tol operate the' jaws, thel upper en'd of a push rod is connected" at 82y with the arm .70 of the jaw 62 and the lower end is' piv- 'otedf at SL1- to a lever 86 "fulcrumed 88 to a bracketl secured to theV floor. A treadle' member 92v` is pivoted at 94 and has, at its outer end, a pin and slot connection9'6 with Consequently, when the outer' end of the trea'dle 92' is pressed upon, the lever 86 will be operated tol push upwardly on therod 80 first to close the jaws 60, upon the heel. Fiirther movementof the vtreadle will cause the jaws and the tread Vface" members'to be lifted With the post 46 to present the breast tace of the heelto the action of the cutter 16; The member 501s shaped toiei'i'ibrace the rear part of' the shoe and to torina guard for' the operators hand 'which holds the rear portionot the v The organization ot" thev Villustrated ma chine is such thaty at the option of the op erator the niachine may be used to' breast transversely straigh'ts heels or transversely eonvexheels. A roll 102 mounted on the post L16 may beset to engage a straight, vertical face i'ormed onthe tront` edge: oit aftrack 104i. lf-he roll 102 is held against the track 104e during ruiward movement ot' the post 46 by a spring); 106 arranged between the bracket 20and an adjustable nut 108 on'- a rod 110 which passes` through the bracket and is pivoted to a collar 112 embracing the shaftl 88.

Then thevroll 102"is'thus located on the trac-k 10-l-,` theV heel iergiven a transversely straf ht breast;-

ALrrang'ed alongsidethoplate;104e is a second plate 1111 having a cam surface on its front edge with which the roll 102 may, at the voption of the operator, be set to engage. As shown in Fig'. 2, the rol is mounted on a shaft 116 to which a sleeve 118 is pinned. The sleeve 118 slides in ak bore formed in a boss 120 and through which the shaft 116 passes. Between the sleeve 118 and the bottom of the bore is a spring 122. On the outers endl` of the shaft 116 is a thumb-head 124 which has a projection 126 arranged to enter a reeess in theboss 120: Als shownin Fig'. 2'; the rolll102engagges the cam surfacev 114"y audi, during' upward movement of the shoe,n the shoe-locating and carrying lpartswzifll be moved first away trom the'cutte'r and then toward' it, causing the cutter to impart a transverse convexizty to the breafit-V tace-ot` the heel; It it is desired to use thel machine for imparting a transversely straight breast. tortlie' heeh. the shoe 'carrier will be' moved outward slightly against the tension of they spring-1i 106 and the" tlmmbhead 124`will= bef-f pulled outwardly and given partial. rotab4 tion so that they projection 126` willv rest against, the outer surface of the boss 120.2,

The roll 102 will: then be located opposite.-
